Setup
- Items needed:
- PC or Laptop
- Raspberry Pi (I used model 2B)
- ADS1015 12bit ADC converter (if you use 1115 which is 16bit, there will be slight changes)
- Breadbord, wires, resistors
- Adafruit assembled Pi T-Cobbler Plus - GPIO Breakout (Optional)
- Circuit setup
- Refer to fritzing diagrams in schematics folder
- Configuration
- SSH, VNC or anyother method of communication enabled between the Raspberry PI and the user PC
- My case was
- Laptop with Ubuntu 16.04 LTS
- Raspberry PI 2B with Raspbian Jessie release 2017-01-11-raspbian-jessie.img
- SSH communication through ethernet cable
- My case was
- SSH, VNC or anyother method of communication enabled between the Raspberry PI and the user PC
- Deployment instructions
- As per the schematics folder
- Connect Raspberry with Adafruit T-Cobbler
- Connect T-Cobbler onto the breadboard
- Connect ADS1015 onto the breadboard
- Do the wirings as described in the schematics folder
- In the circuit diagram I made a note about the location of the UNKNOWN resistor
- As per the schematics folder

- ADS1015 Schematic (Very useful !)
- dev-interface driver at kernel.org
- Voltage divider info
- An excellent tutorial on basic usage of ADS1115 (basicly same as ADS1015), will clarify a lot !
